To all whom it may concern:

Be it known that I, FRANK GLATZEL, a citizen of the United 'States, anda resident of Paterson, in the county of Passaic and State of NewJersey, have invented new and useful Improvements in J acquard-Machinesof which the following is a full, clear, and exact description.

The object of the invention is to provide certain new and usefulimprovements in jacquard machines whereby the bearmgs for the framecarrying the card cylinder are relieved of the weight of the cardcylinder to prevent binding of the frame in the bearings and to insurean easy reciproeating movement of the frame thereby re ducing the wearand tear to a minimum. Another object is to permit of applying theimprovements to a jacquard machine as now generally constructed andwithout requiring changes in the parts thereof.

With these and other objects in view, the invention consists of certainnovel features of construction as hereinafter shown and described andthen specifically pointed out in the claims. 1

A practical embodiment of the invention is represented in theaccompanying drawings forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure 1 is a side elevation of the im provements as applied to ajacquard machine of ordinary construction;

Fig. 2 is an end elevation of the same;

Fig. 3 is an enlarged side elevation of the improvements asapplied,parts being shown in section, on the line 33 of Fig. 2;

Fig. 4 is a sectional plan view of the same on the line 4-4 of Fig. 3;

Fig. 5 is a cross section of the same on the line 55 of Fig. 3;

Fi 6 is a similar view of the same on the line 66 of Fig. 3; and

Fig. 7 is a perspective view ofone of the rails or guideways.

The main frame 10 of the jacquard machine is provided on each side. withbearings 11 in which are mounted to reciprocate rods 12 forming parts ofthe frames or heads 13, in which is journaled the card cylinder 14, toallow the card cylinder to turn in the usual manner. are secured thecams 15 engaged by pins 16 on the vertical reciprocating frame 17 toApplication filed July 12 1919. Serial No. 310,296.

impart a reciprocating movement to the frames 13 and consequently to thecard cylinder 14. The card cylinder 14 is pro vided at one end with theusual wheel 18 engaged by a hook '19 fulcrumed on the frame '10 andserving to turn the card cylinder 14 at the time the latter reciprocatesfrom the right to the left. The construc tion so far shownand describedis the same as now usedin theordinary or standard jacquard machine.

In operation of the jacquard machine, the weight of the card cylinder 14provides a heavy friction in the bearings 11 and consequently the latterand the rods 12 are subjected to heavy wear, and in order to relieve thebearings 11 and the rods 12 of undue strain, the following arrangementis made:

On each of the frames 13 is secured a pivot 25 on which is mounted toturn a roller or wheel 26 mounted to travel in a groove 27 formedlengthwise in the top of a longitudinally extending rail or guideway 28'secured by a bolt 29 to the main frame 10. The bolt 29 extends through aslot 30 formed in the frame 10, and the rail is provided with a lug 31projecting into the slot to holdthe bracket against turning on the bolt29. In practice, the frame is preferably in the form of channel irons,and the face of the rail 28 is provided with a lug 32 fitting into theback groove 33 of the frame to assist in bold ing the rail againstaccidental turning on the bolt 29. The groove 27 is filled withlubricating oil so that-the wheel or roller 26 runs in the lubricant.The roller or wheel 26 is provided with a peripheral groove 35 fromwhich extend openings 36 to the central bore of the wheel to cause someof the lubricant to pass from the groove'35 and the openings 36 to thepivot 25 to insure roper lubrication of the roller or wheel 26 on itspivot 25. It will be noticed that the two rollers or wheels 26 arelocated vertically below the card cylinder 14 and consequently theweight of the card cylinder is sustained by the rollers or wheels 26traveling on the rails or guideways 28 fixed to the main frame of thejacquard machine. It will also be noticed that the rollers 26 travel ina.

tion by their bolts 29 on the main frame 10 b so as to relieve the rods12 and the bearings 11 of undue strain thereby insuring an easyreciprocating movement of the frames 18, carrying the card Cylinder 14.S It Will further be noticed that the rails 28 can be readily attachedto the frame 10-without disturbing other partsof the machine, and therollers or wheels 26 and their pivots can be readily attached to theframes 13 without changing the'construction thereof. a V

a It is understood that the improvement described consists essentiallyof the grooved rails 28 attached by the bolts 29 to the main frame, andthe rollers or wheels 26 traveling in the grooves 27 and journaled onthe pivot 25 secured to the usual frame 13 in which the card cylinder 14is journaled. 7

Having thus described my invention, '1

ters Patent opposite sides of the machine and provided 1} In a jacquardmachine, fixed rails on with grooves filled with lubricatingoiL'androllers journaled on the frame carrying the card cylinder and mounted totravel on the bottoms of'the said grooves, the said rollers I beingdisposed below the card cylinder to sustain the Weight thereof.

2. In a jacquard machine, a card cylinder,

a'reciprocating frame in which the card cylv.

inder is mounted to turn, fixed railsonopposite sides of the machine andextending in the direction of the movement of, the said frame, the saidrails being provided at top With lengthwise extending grooves, androllers journaled on the said frame below the said card cylinder andtraveling on the. bottoms of the said grooves.
